Tool/software:
Dear Team TI,
We are using MSPM0L1105 now for yet another communication module for MBUS, we earlier worked-out with MODBUS.
In that we are using UART0 as one of the peripherals.
The problem is as follows:
When we operate the Device in Debug mode using XDS110 all functions runs flawlessly as expected.
However when device is powered-on in standalone mode without debugger sadly it fails to get even powered-up.
We have a optocoupler based isolation at the UART0, for which we have used a pull-up of 4.7 kOhm at PA18 (the RX pin of MSPM0).
Kindly review the following observation table:
We noticed that this also is used for BSL Invoke, and we suspect that this fact has something to do with this.
We have RC configuration at NRST pin as TI recommends for MSPM0: external 47-kΩ pull-up resistor with a 10-nF pull-down capacitor.
Can you please help us by suggesting possible fixes for this problem?
Thanks and Regards.
